/**
 * Tag-closer extension for CodeMirror.
 *
 * This extension adds an "autoCloseTags" option that can be set to
 * either true to get the default behavior, or an object to further
 * configure its behavior.
 *
 * These are supported options:
 *
 * `whenClosing` (default true)
 *   Whether to autoclose when the '/' of a closing tag is typed.
 * `whenOpening` (default true)
 *   Whether to autoclose the tag when the final '>' of an opening
 *   tag is typed.
 * `dontCloseTags` (default is empty tags for HTML, none for XML)
 *   An array of tag names that should not be autoclosed.
 * `indentTags` (default is block tags for HTML, none for XML)
 *   An array of tag names that should, when opened, cause a
 *   blank line to be added inside the tag, and the blank line and
 *   closing line to be indented.
 *
 * See demos/closetag.html for a usage example.

//
// The option can be set to true to simply enable it, or to a

// configure it. minChars is the minimum amount of characters that should be
// selected for the behavior to occur, and style is the token style to
// apply to the matches. This will be prefixed by "cm-" to create an
// actual CSS class name. If wordsOnly is enabled, the matches will be
// highlighted only if the selected text is a word. showToken, when enabled,
// will cause the current token to be highlighted when nothing is selected.
// delay is used to specify how much time to wait, in milliseconds, before
// highlighting the matches.

// Glue code between CodeMirror and Tern.
//
// Create a CodeMirror.TernServer to wrap an actual Tern server,
// register open documents (CodeMirror.Doc instances) with it, and
// call its methods to activate the assisting functions that Tern
// provides.
//
// Options supported (all optional):
// * defs: An array of JSON definition data structures.
// * plugins: An object mapping plugin names to configuration
//   options.
// * getFile: A function(name, c) that can be used to access files in
//   the project that haven't been loaded yet. Simply do c(null) to
//   indicate that a file is not available.
// * fileFilter: A function(value, docName, doc) that will be applied
//   to documents before passing them on to Tern.
// * switchToDoc: A function(name, doc) that should, when providing a
//   multi-file view, switch the view or focus to the named file.
// * showError: A function(editor, message) that can be used to
//   override the way errors are displayed.
// * completionTip: Customize the content in tooltips for completions.
//   Is passed a single argument—the completion's data as returned by
//   Tern—and may return a string, DOM node, or null to indicate that
//   no tip should be shown. By default the docstring is shown.
// * typeTip: Like completionTip, but for the tooltips shown for type
//   queries.
// * responseFilter: A function(doc, query, request, error, data) that
//   will be applied to the Tern responses before treating them
//
//
// It is possible to run the Tern server in a web worker by specifying
// these additional options:
// * useWorker: Set to true to enable web worker mode. You'll probably
//   want to feature detect the actual value you use here, for example
//   !!window.Worker.
// * workerScript: The main script of the worker. Point this to
//   wherever you are hosting worker.js from this directory.
// * workerDeps: An array of paths pointing (relative to workerScript)
//   to the Acorn and Tern libraries and any Tern plugins you want to
//   load. Or, if you minified those into a single script and included
//   them in the workerScript, simply leave this undefined.

<p>The emacs keybindings are enabled by
including <a href="../keymap/emacs.js">keymap/emacs.js</a> and setting
the <code>keyMap</code> option to <code>"emacs"</code>. Because
CodeMirror's internal API is quite different from Emacs, they are only
a loose approximation of actual emacs bindings, though.</p>

<p>Also note that a lot of browsers disallow certain keys from being
captured. For example, Chrome blocks both Ctrl-W and Ctrl-N, with the
result that idiomatic use of Emacs keys will constantly close your tab
or open a new window.</p>

  <h2 id="overview">Overview</h2>

  <p>CodeMirror is a code-editor component that can be embedded in Web pages. The core library provides <em>only</em> the editor component, no accompanying buttons, auto-completion, or other IDE functionality. It does provide a rich API on top of which such functionality can be straightforwardly implemented. See the <a href="#addons">add-ons</a> included in the distribution, and the <a href="https://github.com/jagthedrummer/codemirror-ui">CodeMirror UI</a> project, for reusable implementations of extra features.</p>

  <p>CodeMirror works with language-specific modes. Modes are JavaScript programs that help color (and optionally indent) text written in a given language.

Select something from here. You'll see that the selection's foreground
color changes to white! Since, by default, CodeMirror only puts an
independent "marker" layer behind the text, you'll need something like
this to change its colour.

Also notice that turning this addon on (with the default style) allows
you to safely give text a background color without screwing up the
visibility of the selection.</textarea></form>

<h2>merge view demo</h2>


<div id=view></div>

<p>The <a href="../doc/manual.html#addon_merge"><code>merge</code></a>
addon provides an interface for displaying and merging diffs,
either <span class=clicky onclick="panes = 2; initUI()">two-way</span>
or <span class=clicky onclick="panes = 3; initUI()">three-way</span>.
The left (or center) pane is editable, and the differences with the
other pane(s) are <span class=clicky
onclick="toggleDifferences()">optionally</span> shown live as you edit
it. In the two-way configuration, there are also options to pad changed
sections to <span class=clicky onclick="connect = connect ? null :
'align'; initUI()">align</span> them, and to <span class=clicky
onclick="collapse = !collapse; initUI()">collapse</span> unchanged
stretches of text.</p>

<p>This addon depends on
the <a href="https://code.google.com/p/google-diff-match-patch/">google-diff-match-patch</a>

<h2>Simple Mode Demo</h2>

<p>The <a href="../addon/mode/simple.js"><code>mode/simple</code></a>
addon allows CodeMirror modes to be specified using a relatively simple
declarative format. This format is not as powerful as writing code
directly against the <a href="../doc/manual.html#modeapi">mode
interface</a>, but is a lot easier to get started with, and
sufficiently expressive for many simple language modes.</p>

<p>This interface is still in flux. It is unlikely to be scrapped or
overhauled completely, so do start writing code against it, but
details might change as it stabilizes, and you might have to tweak
your code when upgrading.</p>

<p>Simple modes (loosely based on
the <a href="https://github.com/mozilla/skywriter/wiki/Common-JavaScript-Syntax-Highlighting-Specification">Common
JavaScript Syntax Highlighting Specification</a>, which never took
off), are state machines, where each state has a number of rules that
match tokens. A rule describes a type of token that may occur in the
current state, and possibly a transition to another state caused by
that token.</p>

<p>The <code>CodeMirror.defineSimpleMode(name, states)</code> method
takes a mode name and an object that describes the mode's states. The
editor below shows an example of such a mode (and is itself
highlighted by the mode shown in it).</p>

<div id="code"></div>

<p>Each state is an array of rules. A rule may have the following properties:</p>

<dl>
  <dt><code><strong>regex</strong>: string | RegExp</code></dt>
  <dd>The regular expression that matches the token. May be a string
  or a regex object. When a regex, the <code>ignoreCase</code> flag
  will be taken into account when matching the token. This regex
  should only capture groups when the <code>token</code> property is
  an array.</dd>
  <dt><code><strong>token</strong></code>: string | null</dt>
  <dd>An optional token style. Multiple styles can be specified by
  separating them with dots or spaces. When the <code>regex</code> for
  this rule captures groups, it must capture <em>all</em> of the
  string (since JS provides no way to find out where a group matched),
  and this property must hold an array of token styles that has one
  style for each matched group.</dd>
  <dt><code><strong>sol</strong></code>: boolean</dt>
  <dd>When true, this token will only match at the start of the line.
  (The <code>^</code> regexp marker doesn't work as you'd expect in
  this context because of limitations in JavaScript's RegExp
  API.)</dd>
  <dt><code><strong>next</strong>: string</code></dt>
  <dd>When a <code>next</code> property is present, the mode will
  transfer to the state named by the property when the token is
  encountered.</dd>
  <dt><code><strong>push</strong>: string</code></dt>
  <dd>Like <code>next</code>, but instead replacing the current state
  by the new state, the current state is kept on a stack, and can be
  returned to with the <code>pop</code> directive.</dd>
  <dt><code><strong>pop</strong>: bool</code></dt>
  <dd>When true, and there is another state on the state stack, will
  cause the mode to pop that state off the stack and transition to
  it.</dd>
  <dt><code><strong>mode</strong>: {spec, end, persistent}</code></dt>
  <dd>Can be used to embed another mode inside a mode. When present,
  must hold an object with a <code>spec</code> property that describes
  the embedded mode, and an optional <code>end</code> end property
  that specifies the regexp that will end the extent of the mode. When
  a <code>persistent</code> property is set (and true), the nested
  mode's state will be preserved between occurrences of the mode.</dd>
  <dt><code><strong>indent</strong>: bool</code></dt>
  <dd>When true, this token changes the indentation to be one unit
  more than the current line's indentation.</dd>
  <dt><code><strong>dedent</strong>: bool</code></dt>
  <dd>When true, this token will pop one scope off the indentation
  stack.</dd>
  <dt><code><strong>dedentIfLineStart</strong>: bool</code></dt>
  <dd>If a token has its <code>dedent</code> property set, it will, by
  default, cause lines where it appears at the start to be dedented.
  Set this property to false to prevent that behavior.</dd>
</dl>

<p>The <code>meta</code> property of the states object is special, and
will not be interpreted as a state. Instead, properties set on it will
be set on the mode, which is useful for properties
like <a href="../doc/manual.html#addon_comment"><code>lineComment</code></a>,
which sets the comment style for a mode. The simple mode addon also
recognizes a few such properties:</p>

<dl>
  <dt><code><strong>dontIndentStates</strong>: array&lt;string&gt;</code></dt>
  <dd>An array of states in which the mode's auto-indentation should
  not take effect. Usually used for multi-line comment and string
  states.</dd>
</dl>

<script id="modecode">/* Example definition of a simple mode that understands a subset of
 * JavaScript:
 */

CodeMirror.defineSimpleMode("simplemode", {
  // The start state contains the rules that are intially used
  start: [

<p>The <a href="../doc/manual.html#addon_simplescrollbars"><code>simplescrollbars</code></a> addon defines two
styles of non-native scrollbars: <a href="javascript:editor.setOption('scrollbarStyle', 'simple')"><code>"simple"</code></a> and <a href="javascript:editor.setOption('scrollbarStyle', 'overlay')"><code>"overlay"</code></a> (click to try), which can be passed to
the <a href="../doc/manual.html#option_scrollbarStyle"><code>scrollbarStyle</code></a> option. These implement
the scrollbar using DOM elements, allowing more control over
its <a href="../addon/scroll/simplescrollbars.css">appearance</a>.</p>

<p>The vim keybindings are enabled by including <code><a
href="../keymap/vim.js">keymap/vim.js</a></code> and setting the
<code>keyMap</code> option to <code>vim</code>.</p>

<p><strong>Features</strong></p>

<ul>
  <li>All common motions and operators, including text objects</li>
  <li>Operator motion orthogonality</li>
  <li>Visual mode - characterwise, linewise, blockwise</li>
  <li>Full macro support (q, @)</li>
  <li>Incremental highlighted search (/, ?, #, *, g#, g*)</li>
  <li>Search/replace with confirm (:substitute, :%s)</li>
  <li>Search history</li>
  <li>Jump lists (Ctrl-o, Ctrl-i)</li>
  <li>Key/command mapping with API (:map, :nmap, :vmap)</li>
  <li>Sort (:sort)</li>
  <li>Marks (`, ')</li>
  <li>:global</li>
  <li>Insert mode behaves identical to base CodeMirror</li>
  <li>Cross-buffer yank/paste</li>
</ul>

<p>For the full list of key mappings and Ex commands, refer to the
<code>defaultKeymap</code> and <code>defaultExCommandMap</code> at the
top of <code><a href="../keymap/vim.js">keymap/vim.js</a></code>.

<p>Note that while the vim mode tries to emulate the most useful
features of vim as faithfully as possible, it does not strive to
become a complete vim implementation</p>

<h2>Script compression helper</h2>

    <p>To optimize loading CodeMirror, especially when including a
    bunch of different modes, it is recommended that you combine and
    minify (and preferably also gzip) the scripts. This page makes
    those first two steps very easy. Simply select the version and
    scripts you need in the form below, and
    click <strong>Compress</strong> to download the minified script
    file.</p>

    <form id="form" action="http://marijnhaverbeke.nl/uglifyjs" method="post" onsubmit="generateHeader();">
      <input type="hidden" id="download" name="download" value="codemirror-compressed.js"/>

<h2 id=top>(Re-) Implementing A Syntax-Highlighting Editor in JavaScript</h2>

<p style="font-size: 85%" id="intro">
  <strong>Topic:</strong> JavaScript, code editor implementation<br>
  <strong>Author:</strong> Marijn Haverbeke<br>
  <strong>Date:</strong> March 2nd 2011 (updated November 13th 2011)
</p>

<p style="padding: 0 3em 0 2em"><strong>Caution</strong>: this text was written briefly after
version 2 was initially written. It no longer (even including the
update at the bottom) fully represents the current implementation. I'm
leaving it here as a historic document. For more up-to-date
information, look at the entries
tagged <a href="http://marijnhaverbeke.nl/blog/#cm-internals">cm-internals</a>
on my blog.</p>

<p>This is a followup to
my <a href="http://codemirror.net/story.html">Brutal Odyssey to the
Dark Side of the DOM Tree</a> story. That one describes the
mind-bending process of implementing (what would become) CodeMirror 1.
This one describes the internals of CodeMirror 2, a complete rewrite
and rethink of the old code base. I wanted to give this piece another
Hunter Thompson copycat subtitle, but somehow that would be out of
place—the process this time around was one of straightforward
engineering, requiring no serious mind-bending whatsoever.</p>

<p>So, what is wrong with CodeMirror 1? I'd estimate, by mailing list
activity and general search-engine presence, that it has been
integrated into about a thousand systems by now. The most prominent
one, since a few weeks,
being <a href="http://googlecode.blogspot.com/2011/01/make-quick-fixes-quicker-on-google.html">Google
code's project hosting</a>. It works, and it's being used widely.</p>

<p>Still, I did not start replacing it because I was bored. CodeMirror
1 was heavily reliant on <code>designMode</code>
or <code>contentEditable</code> (depending on the browser). Neither of
these are well specified (HTML5 tries
to <a href="http://www.w3.org/TR/html5/editing.html#contenteditable">specify</a>
their basics), and, more importantly, they tend to be one of the more
obscure and buggy areas of browser functionality—CodeMirror, by using
this functionality in a non-typical way, was constantly running up
against browser bugs. WebKit wouldn't show an empty line at the end of
the document, and in some releases would suddenly get unbearably slow.
Firefox would show the cursor in the wrong place. Internet Explorer
would insist on linkifying everything that looked like a URL or email
address, a behaviour that can't be turned off. Some bugs I managed to
work around (which was often a frustrating, painful process), others,
such as the Firefox cursor placement, I gave up on, and had to tell
user after user that they were known problems, but not something I
could help.</p>

<p>Also, there is the fact that <code>designMode</code> (which seemed
to be less buggy than <code>contentEditable</code> in Webkit and
Firefox, and was thus used by CodeMirror 1 in those browsers) requires
a frame. Frames are another tricky area. It takes some effort to
prevent getting tripped up by domain restrictions, they don't
initialize synchronously, behave strangely in response to the back
button, and, on several browsers, can't be moved around the DOM
without having them re-initialize. They did provide a very nice way to
namespace the library, though—CodeMirror 1 could freely pollute the
namespace inside the frame.</p>

<p>Finally, working with an editable document means working with
selection in arbitrary DOM structures. Internet Explorer (8 and
before) has an utterly different (and awkward) selection API than all
of the other browsers, and even among the different implementations of
<code>document.selection</code>, details about how exactly a selection
is represented vary quite a bit. Add to that the fact that Opera's
selection support tended to be very buggy until recently, and you can
imagine why CodeMirror 1 contains 700 lines of selection-handling
code.</p>

<p>And that brings us to the main issue with the CodeMirror 1
code base: The proportion of browser-bug-workarounds to real
application code was getting dangerously high. By building on top of a
few dodgy features, I put the system in a vulnerable position—any
incompatibility and bugginess in these features, I had to paper over
with my own code. Not only did I have to do some serious stunt-work to
get it to work on older browsers (as detailed in the
previous <a href="http://codemirror.net/story.html">story</a>), things
also kept breaking in newly released versions, requiring me to come up
with <em>new</em> scary hacks in order to keep up. This was starting
to lose its appeal.</p>

<section id=approach>
  <h2>General Approach</h2>

<p>What CodeMirror 2 does is try to sidestep most of the hairy hacks
that came up in version 1. I owe a lot to the
<a href="http://ace.ajax.org">ACE</a> editor for inspiration on how to
approach this.</p>

<p>I absolutely did not want to be completely reliant on key events to
generate my input. Every JavaScript programmer knows that key event
information is horrible and incomplete. Some people (most awesomely
Mihai Bazon with <a href="http://ymacs.org">Ymacs</a>) have been able
to build more or less functioning editors by directly reading key
events, but it takes a lot of work (the kind of never-ending, fragile
work I described earlier), and will never be able to properly support
things like multi-keystoke international character
input. <a href="#keymap" class="update">[see below for caveat]</a></p>

<p>So what I do is focus a hidden textarea, and let the browser
believe that the user is typing into that. What we show to the user is
a DOM structure we built to represent his document. If this is updated
quickly enough, and shows some kind of believable cursor, it feels
like a real text-input control.</p>

<p>Another big win is that this DOM representation does not have to
span the whole document. Some CodeMirror 1 users insisted that they
needed to put a 30 thousand line XML document into CodeMirror. Putting
all that into the DOM takes a while, especially since, for some
reason, an editable DOM tree is slower than a normal one on most
browsers. If we have full control over what we show, we must only
ensure that the visible part of the document has been added, and can
do the rest only when needed. (Fortunately, the <code>onscroll</code>
event works almost the same on all browsers, and lends itself well to
displaying things only as they are scrolled into view.)</p>
</section>
<section id="input">
  <h2>Input</h2>

<p>ACE uses its hidden textarea only as a text input shim, and does
all cursor movement and things like text deletion itself by directly
handling key events. CodeMirror's way is to let the browser do its
thing as much as possible, and not, for example, define its own set of
key bindings. One way to do this would have been to have the whole
document inside the hidden textarea, and after each key event update
the display DOM to reflect what's in that textarea.</p>

<p>That'd be simple, but it is not realistic. For even medium-sized
document the editor would be constantly munging huge strings, and get
terribly slow. What CodeMirror 2 does is put the current selection,
along with an extra line on the top and on the bottom, into the
textarea.</p>

<p>This means that the arrow keys (and their ctrl-variations), home,
end, etcetera, do not have to be handled specially. We just read the
cursor position in the textarea, and update our cursor to match it.
Also, copy and paste work pretty much for free, and people get their
native key bindings, without any special work on my part. For example,
I have emacs key bindings configured for Chrome and Firefox. There is
no way for a script to detect this. <a class="update"
href="#keymap">[no longer the case]</a></p>

<p>Of course, since only a small part of the document sits in the
textarea, keys like page up and ctrl-end won't do the right thing.
CodeMirror is catching those events and handling them itself.</p>
</section>
<section id="selection">
  <h2>Selection</h2>

<p>Getting and setting the selection range of a textarea in modern
browsers is trivial—you just use the <code>selectionStart</code>
and <code>selectionEnd</code> properties. On IE you have to do some
insane stuff with temporary ranges and compensating for the fact that
moving the selection by a 'character' will treat \r\n as a single
character, but even there it is possible to build functions that
reliably set and get the selection range.</p>

<p>But consider this typical case: When I'm somewhere in my document,
press shift, and press the up arrow, something gets selected. Then, if
I, still holding shift, press the up arrow again, the top of my
selection is adjusted. The selection remembers where its <em>head</em>
and its <em>anchor</em> are, and moves the head when we shift-move.
This is a generally accepted property of selections, and done right by
every editing component built in the past twenty years.</p>

<p>But not something that the browser selection APIs expose.</p>

<p>Great. So when someone creates an 'upside-down' selection, the next
time CodeMirror has to update the textarea, it'll re-create the
selection as an 'upside-up' selection, with the anchor at the top, and
the next cursor motion will behave in an unexpected way—our second
up-arrow press in the example above will not do anything, since it is
interpreted in exactly the same way as the first.</p>

<p>No problem. We'll just, ehm, detect that the selection is
upside-down (you can tell by the way it was created), and then, when
an upside-down selection is present, and a cursor-moving key is
pressed in combination with shift, we quickly collapse the selection
in the textarea to its start, allow the key to take effect, and then
combine its new head with its old anchor to get the <em>real</em>
selection.</p>

<p>In short, scary hacks could not be avoided entirely in CodeMirror
2.</p>

<p>And, the observant reader might ask, how do you even know that a
key combo is a cursor-moving combo, if you claim you support any
native key bindings? Well, we don't, but we can learn. The editor
keeps a set known cursor-movement combos (initialized to the
predictable defaults), and updates this set when it observes that
pressing a certain key had (only) the effect of moving the cursor.
This, of course, doesn't work if the first time the key is used was
for extending an inverted selection, but it works most of the
time.</p>
</section>
<section id="update">
  <h2>Intelligent Updating</h2>

<p>One thing that always comes up when you have a complicated internal
state that's reflected in some user-visible external representation
(in this case, the displayed code and the textarea's content) is
keeping the two in sync. The naive way is to just update the display
every time you change your state, but this is not only error prone
(you'll forget), it also easily leads to duplicate work on big,
composite operations. Then you start passing around flags indicating
whether the display should be updated in an attempt to be efficient
again and, well, at that point you might as well give up completely.</p>

<p>I did go down that road, but then switched to a much simpler model:
simply keep track of all the things that have been changed during an
action, and then, only at the end, use this information to update the
user-visible display.</p>

<p>CodeMirror uses a concept of <em>operations</em>, which start by
calling a specific set-up function that clears the state and end by
calling another function that reads this state and does the required
updating. Most event handlers, and all the user-visible methods that
change state are wrapped like this. There's a method
called <code>operation</code> that accepts a function, and returns
another function that wraps the given function as an operation.</p>

<p>It's trivial to extend this (as CodeMirror does) to detect nesting,
and, when an operation is started inside an operation, simply
increment the nesting count, and only do the updating when this count
reaches zero again.</p>

<p>If we have a set of changed ranges and know the currently shown
range, we can (with some awkward code to deal with the fact that
changes can add and remove lines, so we're dealing with a changing
coordinate system) construct a map of the ranges that were left
intact. We can then compare this map with the part of the document
that's currently visible (based on scroll offset and editor height) to
determine whether something needs to be updated.</p>

<p>CodeMirror uses two update algorithms—a full refresh, where it just
discards the whole part of the DOM that contains the edited text and
rebuilds it, and a patch algorithm, where it uses the information
about changed and intact ranges to update only the out-of-date parts
of the DOM. When more than 30 percent (which is the current heuristic,
might change) of the lines need to be updated, the full refresh is
chosen (since it's faster to do than painstakingly finding and
updating all the changed lines), in the other case it does the
patching (so that, if you scroll a line or select another character,
the whole screen doesn't have to be
re-rendered). <span class="update">[the full-refresh
algorithm was dropped, it wasn't really faster than the patching
one]</span></p>

<p>All updating uses <code>innerHTML</code> rather than direct DOM
manipulation, since that still seems to be by far the fastest way to
build documents. There's a per-line function that combines the
highlighting, <a href="manual.html#markText">marking</a>, and
selection info for that line into a snippet of HTML. The patch updater
uses this to reset individual lines, the refresh updater builds an
HTML chunk for the whole visible document at once, and then uses a
single <code>innerHTML</code> update to do the refresh.</p>
</section>
<section id="parse">
  <h2>Parsers can be Simple</h2>

<p>When I wrote CodeMirror 1, I
thought <a href="http://codemirror.net/story.html#parser">interruptable
parsers</a> were a hugely scary and complicated thing, and I used a
bunch of heavyweight abstractions to keep this supposed complexity
under control: parsers
were <a href="http://bob.pythonmac.org/archives/2005/07/06/iteration-in-javascript/">iterators</a>
that consumed input from another iterator, and used funny
closure-resetting tricks to copy and resume themselves.</p>

<p>This made for a rather nice system, in that parsers formed strictly
separate modules, and could be composed in predictable ways.
Unfortunately, it was quite slow (stacking three or four iterators on
top of each other), and extremely intimidating to people not used to a
functional programming style.</p>

<p>With a few small changes, however, we can keep all those
advantages, but simplify the API and make the whole thing less
indirect and inefficient. CodeMirror
2's <a href="manual.html#modeapi">mode API</a> uses explicit state
objects, and makes the parser/tokenizer a function that simply takes a
state and a character stream abstraction, advances the stream one
token, and returns the way the token should be styled. This state may
be copied, optionally in a mode-defined way, in order to be able to
continue a parse at a given point. Even someone who's never touched a
lambda in his life can understand this approach. Additionally, far
fewer objects are allocated in the course of parsing now.</p>

<p>The biggest speedup comes from the fact that the parsing no longer
has to touch the DOM though. In CodeMirror 1, on an older browser, you
could <em>see</em> the parser work its way through the document,
managing some twenty lines in each 50-millisecond time slice it got. It
was reading its input from the DOM, and updating the DOM as it went
along, which any experienced JavaScript programmer will immediately
spot as a recipe for slowness. In CodeMirror 2, the parser usually
finishes the whole document in a single 100-millisecond time slice—it
manages some 1500 lines during that time on Chrome. All it has to do
is munge strings, so there is no real reason for it to be slow
anymore.</p>
</section>
<section id="summary">
  <h2>What Gives?</h2>

<p>Given all this, what can you expect from CodeMirror 2?</p>

<ul>

<li><strong>Small.</strong> the base library is
some <span class="update">45k</span> when minified
now, <span class="update">17k</span> when gzipped. It's smaller than
its own logo.</li>

<li><strong>Lightweight.</strong> CodeMirror 2 initializes very
quickly, and does almost no work when it is not focused. This means
you can treat it almost like a textarea, have multiple instances on a
page without trouble.</li>

<li><strong>Huge document support.</strong> Since highlighting is
really fast, and no DOM structure is being built for non-visible
content, you don't have to worry about locking up your browser when a
user enters a megabyte-sized document.</li>

<li><strong>Extended API.</strong> Some things kept coming up in the
mailing list, such as marking pieces of text or lines, which were
extremely hard to do with CodeMirror 1. The new version has proper
support for these built in.</li>

<li><strong>Tab support.</strong> Tabs inside editable documents were,
for some reason, a no-go. At least six different people announced they
were going to add tab support to CodeMirror 1, none survived (I mean,
none delivered a working version). CodeMirror 2 no longer removes tabs
from your document.</li>

<li><strong>Sane styling.</strong> <code>iframe</code> nodes aren't
really known for respecting document flow. Now that an editor instance
is a plain <code>div</code> element, it is much easier to size it to
fit the surrounding elements. You don't even have to make it scroll if
you do not <a href="../demo/resize.html">want to</a>.</li>

</ul>

<p>On the downside, a CodeMirror 2 instance is <em>not</em> a native
editable component. Though it does its best to emulate such a
component as much as possible, there is functionality that browsers
just do not allow us to hook into. Doing select-all from the context
menu, for example, is not currently detected by CodeMirror.</p>

<p id="changes" style="margin-top: 2em;"><span style="font-weight:
bold">[Updates from November 13th 2011]</span> Recently, I've made
some changes to the codebase that cause some of the text above to no
longer be current. I've left the text intact, but added markers at the
passages that are now inaccurate. The new situation is described
below.</p>
</section>
<section id="btree">
  <h2>Content Representation</h2>

<p>The original implementation of CodeMirror 2 represented the
document as a flat array of line objects. This worked well—splicing
arrays will require the part of the array after the splice to be
moved, but this is basically just a simple <code>memmove</code> of a
bunch of pointers, so it is cheap even for huge documents.</p>

<p>However, I recently added line wrapping and code folding (line
collapsing, basically). Once lines start taking up a non-constant
amount of vertical space, looking up a line by vertical position
(which is needed when someone clicks the document, and to determine
the visible part of the document during scrolling) can only be done
with a linear scan through the whole array, summing up line heights as
you go. Seeing how I've been going out of my way to make big documents
fast, this is not acceptable.</p>

<p>The new representation is based on a B-tree. The leaves of the tree
contain arrays of line objects, with a fixed minimum and maximum size,
and the non-leaf nodes simply hold arrays of child nodes. Each node
stores both the amount of lines that live below them and the vertical
space taken up by these lines. This allows the tree to be indexed both
by line number and by vertical position, and all access has
logarithmic complexity in relation to the document size.</p>

<p>I gave line objects and tree nodes parent pointers, to the node
above them. When a line has to update its height, it can simply walk
these pointers to the top of the tree, adding or subtracting the
difference in height from each node it encounters. The parent pointers
also make it cheaper (in complexity terms, the difference is probably
tiny in normal-sized documents) to find the current line number when
given a line object. In the old approach, the whole document array had
to be searched. Now, we can just walk up the tree and count the sizes
of the nodes coming before us at each level.</p>

<p>I chose B-trees, not regular binary trees, mostly because they
allow for very fast bulk insertions and deletions. When there is a big
change to a document, it typically involves adding, deleting, or
replacing a chunk of subsequent lines. In a regular balanced tree, all
these inserts or deletes would have to be done separately, which could
be really expensive. In a B-tree, to insert a chunk, you just walk
down the tree once to find where it should go, insert them all in one
shot, and then break up the node if needed. This breaking up might
involve breaking up nodes further up, but only requires a single pass
back up the tree. For deletion, I'm somewhat lax in keeping things
balanced—I just collapse nodes into a leaf when their child count goes
below a given number. This means that there are some weird editing
patterns that may result in a seriously unbalanced tree, but even such
an unbalanced tree will perform well, unless you spend a day making
strangely repeating edits to a really big document.</p>
</section>
<section id="keymap">
  <h2>Keymaps</h2>

<p><a href="#approach">Above</a>, I claimed that directly catching key
events for things like cursor movement is impractical because it
requires some browser-specific kludges. I then proceeded to explain
some awful <a href="#selection">hacks</a> that were needed to make it
possible for the selection changes to be detected through the
textarea. In fact, the second hack is about as bad as the first.</p>

<p>On top of that, in the presence of user-configurable tab sizes and
collapsed and wrapped lines, lining up cursor movement in the textarea
with what's visible on the screen becomes a nightmare. Thus, I've
decided to move to a model where the textarea's selection is no longer
depended on.</p>

<p>So I moved to a model where all cursor movement is handled by my
own code. This adds support for a goal column, proper interaction of
cursor movement with collapsed lines, and makes it possible for
vertical movement to move through wrapped lines properly, instead of
just treating them like non-wrapped lines.</p>

<p>The key event handlers now translate the key event into a string,
something like <code>Ctrl-Home</code> or <code>Shift-Cmd-R</code>, and
use that string to look up an action to perform. To make keybinding
customizable, this lookup goes through
a <a href="manual.html#option_keyMap">table</a>, using a scheme that
allows such tables to be chained together (for example, the default
Mac bindings fall through to a table named 'emacsy', which defines
basic Emacs-style bindings like <code>Ctrl-F</code>, and which is also
used by the custom Emacs bindings).</p>

<p>A new
option <a href="manual.html#option_extraKeys"><code>extraKeys</code></a>
allows ad-hoc keybindings to be defined in a much nicer way than what
was possible with the
old <a href="manual.html#option_onKeyEvent"><code>onKeyEvent</code></a>
callback. You simply provide an object mapping key identifiers to
functions, instead of painstakingly looking at raw key events.</p>

<p>Built-in commands map to strings, rather than functions, for
example <code>"goLineUp"</code> is the default action bound to the up
arrow key. This allows new keymaps to refer to them without
duplicating any code. New commands can be defined by assigning to
the <code>CodeMirror.commands</code> object, which maps such commands
to functions.</p>

<p>The hidden textarea now only holds the current selection, with no
extra characters around it. This has a nice advantage: polling for
input becomes much, much faster. If there's a big selection, this text
does not have to be read from the textarea every time—when we poll,
just noticing that something is still selected is enough to tell us
that no new text was typed.</p>

<p>The reason that cheap polling is important is that many browsers do
not fire useful events on IME (input method engine) input, which is
the thing where people inputting a language like Japanese or Chinese
use multiple keystrokes to create a character or sequence of
characters. Most modern browsers fire <code>input</code> when the
composing is finished, but many don't fire anything when the character
is updated <em>during</em> composition. So we poll, whenever the
editor is focused, to provide immediate updates of the display.</p>

<h2>Reporting bugs effectively</h2>

<div class="left">

<p>So you found a problem in CodeMirror. By all means, report it! Bug
reports from users are the main drive behind improvements to
CodeMirror. But first, please read over these points:</p>

<ol>
  <li>CodeMirror is maintained by volunteers. They don't owe you
  anything, so be polite. Reports with an indignant or belligerent
  tone tend to be moved to the bottom of the pile.</li>

  <li>Include information about <strong>the browser in which the
  problem occurred</strong>. Even if you tested several browsers, and
  the problem occurred in all of them, mention this fact in the bug
  report. Also include browser version numbers and the operating
  system that you're on.</li>

  <li>Mention which release of CodeMirror you're using. Preferably,
  try also with the current development snapshot, to ensure the
  problem has not already been fixed.</li>

  <li>Mention very precisely what went wrong. "X is broken" is not a
  good bug report. What did you expect to happen? What happened
  instead? Describe the exact steps a maintainer has to take to make
  the problem occur. We can not fix something that we can not
  observe.</li>

  <li>If the problem can not be reproduced in any of the demos
  included in the CodeMirror distribution, please provide an HTML
  document that demonstrates the problem. The best way to do this is
  to go to <a href="http://jsbin.com/ihunin/1/edit">jsbin.com</a>, enter
  it there, press save, and include the resulting link in your bug
  report.</li>

  </ul>
</div>

<article>

<h2>Upgrading to v2.2</h2>

<p>There are a few things in the 2.2 release that require some care
when upgrading.</p>

<h3>No more default.css</h3>

<p>The default theme is now included
in <a href="../lib/codemirror.css"><code>codemirror.css</code></a>, so
you do not have to included it separately anymore. (It was tiny, so
even if you're not using it, the extra data overhead is negligible.)

<h3>Different key customization</h3>

<p>CodeMirror has moved to a system
where <a href="manual.html#option_keyMap">keymaps</a> are used to
bind behavior to keys. This means <a href="../demo/emacs.html">custom
bindings</a> are now possible.</p>

<p>Three options that influenced key
behavior, <code>tabMode</code>, <code>enterMode</code>,
and <code>smartHome</code>, are no longer supported. Instead, you can
provide custom bindings to influence the way these keys act. This is
done through the
new <a href="manual.html#option_extraKeys"><code>extraKeys</code></a>
option, which can hold an object mapping key names to functionality. A
simple example would be:</p>

<pre>  extraKeys: {
    "Ctrl-S": function(instance) { saveText(instance.getValue()); },
    "Ctrl-/": "undo"
  }</pre>

<p>Keys can be mapped either to functions, which will be given the
editor instance as argument, or to strings, which are mapped through
functions through the <code>CodeMirror.commands</code> table, which
contains all the built-in editing commands, and can be inspected and
extended by external code.</p>

<p>By default, the <code>Home</code> key is bound to
the <code>"goLineStartSmart"</code> command, which moves the cursor to
the first non-whitespace character on the line. You can set do this to
make it always go to the very start instead:</p>

<pre>  extraKeys: {"Home": "goLineStart"}</pre>

<p>Similarly, <code>Enter</code> is bound
to <code>"newlineAndIndent"</code> by default. You can bind it to
something else to get different behavior. To disable special handling
completely and only get a newline character inserted, you can bind it
to <code>false</code>:</p>

<pre>  extraKeys: {"Enter": false}</pre>

<p>The same works for <code>Tab</code>. If you don't want CodeMirror
to handle it, bind it to <code>false</code>. The default behaviour is
to indent the current line more (<code>"indentMore"</code> command),
and indent it less when shift is held (<code>"indentLess"</code>).
There are also <code>"indentAuto"</code> (smart indent)
and <code>"insertTab"</code> commands provided for alternate
behaviors. Or you can write your own handler function to do something
different altogether.</p>

<h3>Tabs</h3>

<p>Handling of tabs changed completely. The display width of tabs can
now be set with the <code>tabSize</code> option, and tabs can
be <a href="../demo/visibletabs.html">styled</a> by setting CSS rules
for the <code>cm-tab</code> class.</p>

<p>The default width for tabs is now 4, as opposed to the 8 that is
hard-wired into browsers. If you are relying on 8-space tabs, make
sure you explicitly set <code>tabSize: 8</code> in your options.</p>

<h2 id=upgrade>Upgrading to version 3</h2>

<p>Version 3 does not depart too much from 2.x API, and sites that use
CodeMirror in a very simple way might be able to upgrade without
trouble. But it does introduce a number of incompatibilities. Please
at least skim this text before upgrading.</p>

<p>Note that <strong>version 3 drops full support for Internet
Explorer 7</strong>. The editor will mostly work on that browser, but
it'll be significantly glitchy.</p>

<section id=dom>
  <h2>DOM structure</h2>

<p>This one is the most likely to cause problems. The internal
structure of the editor has changed quite a lot, mostly to implement a
new scrolling model.</p>

<p>Editor height is now set on the outer wrapper element (CSS
class <code>CodeMirror</code>), not on the scroller element
(<code>CodeMirror-scroll</code>).</p>

<p>Other nodes were moved, dropped, and added. If you have any code
that makes assumptions about the internal DOM structure of the editor,
you'll have to re-test it and probably update it to work with v3.</p>

<p>See the <a href="manual.html#styling">styling section</a> of the
manual for more information.</p>
</section>
<section id=gutters>
  <h2>Gutter model</h2>

<p>In CodeMirror 2.x, there was a single gutter, and line markers
created with <code>setMarker</code> would have to somehow coexist with
the line numbers (if present). Version 3 allows you to specify an
array of gutters, <a href="manual.html#option_gutters">by class
name</a>,
use <a href="manual.html#setGutterMarker"><code>setGutterMarker</code></a>
to add or remove markers in individual gutters, and clear whole
gutters
with <a href="manual.html#clearGutter"><code>clearGutter</code></a>.
Gutter markers are now specified as DOM nodes, rather than HTML
snippets.</p>

<p>The gutters no longer horizontally scrolls along with the content.
The <code>fixedGutter</code> option was removed (since it is now the
only behavior).</p>

<pre data-lang="text/html">
&lt;style>
  /* Define a gutter style */
  .note-gutter { width: 3em; background: cyan; }
&lt;/style>
&lt;script>
  // Create an instance with two gutters -- line numbers and notes
  var cm = new CodeMirror(document.body, {
    gutters: ["note-gutter", "CodeMirror-linenumbers"],
    lineNumbers: true
  });
  // Add a note to line 0
  cm.setGutterMarker(0, "note-gutter", document.createTextNode("hi"));
&lt;/script>
</pre>
</section>
<section id=events>
  <h2>Event handling</h2>

<p>Most of the <code>onXYZ</code> options have been removed. The same
effect is now obtained by calling
the <a href="manual.html#on"><code>on</code></a> method with a string
identifying the event type. Multiple handlers can now be registered
(and individually unregistered) for an event, and objects such as line
handlers now also expose events. See <a href="manual.html#events">the
full list here</a>.</p>

<p>(The <code>onKeyEvent</code> and <code>onDragEvent</code> options,
which act more as hooks than as event handlers, are still there in
their old form.)</p>

<pre data-lang="javascript">
cm.on("change", function(cm, change) {
  console.log("something changed! (" + change.origin + ")");
});
</pre>
</section>
<section id=marktext>
  <h2>markText method arguments</h2>

<p>The <a href="manual.html#markText"><code>markText</code></a> method
(which has gained some interesting new features, such as creating
atomic and read-only spans, or replacing spans with widgets) no longer
takes the CSS class name as a separate argument, but makes it an
optional field in the options object instead.</p>

<pre data-lang="javascript">
// Style first ten lines, and forbid the cursor from entering them
cm.markText({line: 0, ch: 0}, {line: 10, ch: 0}, {
  className: "magic-text",
  inclusiveLeft: true,
  atomic: true
});
</pre>
</section>
<section id=folding>
  <h2>Line folding</h2>

<p>The interface for hiding lines has been
removed. <a href="manual.html#markText"><code>markText</code></a> can
now be used to do the same in a more flexible and powerful way.</p>

<p>The <a href="../demo/folding.html">folding script</a> has been
updated to use the new interface, and should now be more robust.</p>

<pre data-lang="javascript">
// Fold a range, replacing it with the text "??"
var range = cm.markText({line: 4, ch: 2}, {line: 8, ch: 1}, {
  replacedWith: document.createTextNode("??"),
  // Auto-unfold when cursor moves into the range
  clearOnEnter: true
});
// Get notified when auto-unfolding
CodeMirror.on(range, "clear", function() {
  console.log("boom");
});
</pre>
</section>
<section id=lineclass>
  <h2>Line CSS classes</h2>

<p>The <code>setLineClass</code> method has been replaced
by <a href="manual.html#addLineClass"><code>addLineClass</code></a>
and <a href="manual.html#removeLineClass"><code>removeLineClass</code></a>,
which allow more modular control over the classes attached to a line.</p>

<pre data-lang="javascript">
var marked = cm.addLineClass(10, "background", "highlighted-line");
setTimeout(function() {
  cm.removeLineClass(marked, "background", "highlighted-line");
});
</pre>
</section>
<section id=positions>
  <h2>Position properties</h2>

<p>All methods that take or return objects that represent screen
positions now use <code>{left, top, bottom, right}</code> properties
(not always all of them) instead of the <code>{x, y, yBot}</code> used
by some methods in v2.x.</p>

<p>Affected methods
are <a href="manual.html#cursorCoords"><code>cursorCoords</code></a>, <a href="manual.html#charCoords"><code>charCoords</code></a>, <a href="manual.html#coordsChar"><code>coordsChar</code></a>,
and <a href="manual.html#getScrollInfo"><code>getScrollInfo</code></a>.</p>
</section>
<section id=matchbrackets>
  <h2>Bracket matching no longer in core</h2>

<p>The <a href="manual.html#addon_matchbrackets"><code>matchBrackets</code></a>
option is no longer defined in the core editor.
Load <code>addon/edit/matchbrackets.js</code> to enable it.</p>
</section>
<section id=modes>
  <h2>Mode management</h2>

<p>The <code>CodeMirror.listModes</code>
and <code>CodeMirror.listMIMEs</code> functions, used for listing
defined modes, are gone. You are now encouraged to simply
inspect <code>CodeMirror.modes</code> (mapping mode names to mode
constructors) and <code>CodeMirror.mimeModes</code> (mapping MIME
strings to mode specs).</p>
</section>
<section id=new>
  <h2>New features</h2>

<p>Some more reasons to upgrade to version 3.</p>

<ul>
  <li>Bi-directional text support. CodeMirror will now mostly do the
  right thing when editing Arabic or Hebrew text.</li>
  <li>Arbitrary line heights. Using fonts with different heights
  inside the editor (whether off by one pixel or fifty) is now
  supported and handled gracefully.</li>
  <li>In-line widgets. See <a href="../demo/widget.html">the demo</a>
  and <a href="manual.html#addLineWidget">the docs</a>.</li>
  <li>Defining custom options
  with <a href="manual.html#defineOption"><code>CodeMirror.defineOption</code></a>.</li>
</ul>

<article>

<h2 id=upgrade>Upgrading to version 4</h2>

<p>CodeMirror 4's interface is <em>very</em> close version 3, but it
does fix a few awkward details in a backwards-incompatible ways. At
least skim the text below before upgrading.</p>

<section id=multisel><h2>Multiple selections</h2>

<p>The main new feature in version 4 is multiple selections. The
single-selection variants of methods are still there, but now
typically act only on the <em>primary</em> selection (usually the last
one added).</p>

<p>The exception to this
is <a href="manual.html#getSelection"><strong><code>getSelection</code></strong></a>,
which will now return the content of <em>all</em> selections
(separated by newlines, or whatever <code>lineSep</code> parameter you passed
it).</p>

</section>

<section id=beforeSelectionChange><h2>The beforeSelectionChange event</h2>

<p>This event still exists, but the object it is passed has
a <a href="manual.html#event_beforeSelectionChange">completely new
interface</a>, because such changes now concern multiple
selections.</p>

</section>

<section id=replaceSelection><h2>replaceSelection's collapsing behavior</h2>

<p>By
default, <a href="manual.html#replaceSelection"><code>replaceSelection</code></a>
would leave the newly inserted text selected. This is only rarely what
you want, and also (slightly) more expensive in the new model, so the
default was changed to <code>"end"</code>, meaning the old behavior
must be explicitly specified by passing a second argument
of <code>"around"</code>.</p>

</section>

<section id=changeEvent><h2>change event data</h2>

<p>Rather than forcing client code to follow <code>next</code>
pointers from one change object to the next, the library will now
simply fire
multiple <a href="manual.html#event_change"><code>"change"</code></a>
events. Existing code will probably continue to work unmodified.</p>

</section>

<section id=showIfHidden><h2>showIfHidden option to line widgets</h2>

<p>This option, which conceptually caused line widgets to be visible
even if their line was hidden, was never really well-defined, and was
buggy from the start. It would be a rather expensive feature, both in
code complexity and run-time performance, to implement properly. It
has been dropped entirely in 4.0.</p>

</section>

<section id=module><h2>Module loaders</h2>

<p>All modules in the CodeMirror distribution are now wrapped in a
shim function to make them compatible with both AMD
(<a href="http://requirejs.org">requirejs</a>) and CommonJS (as used
by <a href="http://nodejs.org/">node</a>
and <a href="http://browserify.org/">browserify</a>) module loaders.
When neither of these is present, they fall back to simply using the
global <code>CodeMirror</code> variable.</p>

<p>If you have a module loader present in your environment, CodeMirror
will attempt to use it, and you might need to change the way you load
CodeMirror modules.</p>

</section>

<section id=shareddata><h2>Mutating shared data structures</h2>

<p>Data structures produced by the library should not be mutated
unless explicitly allowed, in general. This is slightly more strict in
4.0 than it was in earlier versions, which copied the position objects
returned by <a href="manual.html#getCursor"><code>getCursor</code></a>
for nebulous, historic reasons. In 4.0, mutating these
objects <em>will</em> corrupt your editor's selection.</p>

</section>

<section id=deprecated><h2>Deprecated interfaces dropped</h2>

<p>A few properties and methods that have been deprecated for a while
are now gone. Most notably, the <code>onKeyEvent</code>
and <code>onDragEvent</code> options (use the
corresponding <a href="manual.html#event_dom">events</a> instead).</p>

<p>Two silly methods, which were mostly there to stay close to the 0.x
API, <code>setLine</code> and <code>removeLine</code> are now gone.
Use the more
flexible <a href="manual.html#replaceRange"><code>replaceRange</code></a>
method instead.</p>

<p>The long names for folding and completing functions
(<code>CodeMirror.braceRangeFinder</code>, <code>CodeMirror.javascriptHint</code>,
etc) are also gone

    <p>Simple mode that tries to handle APL as well as it can.</p>
    <p>It attempts to label functions/operators based upon
    monadic/dyadic usage (but this is far from fully fleshed out).
    This means there are meaningful classnames so hover states can
    have popups etc.</p>

  /** A template trait for traversable collections of type `Traversable[A]`.
   *  
   *  $traversableInfo
   *  @define mutability
   *  @define traversableInfo
   *  This is a base trait of all kinds of $mutability Scala collections. It
   *  implements the behavior common to all collections, in terms of a method
   *  `foreach` with signature:
   * {{{
   *     def foreach[U](f: Elem => U): Unit
   * }}}
   *  Collection classes mixing in this trait provide a concrete 
   *  `foreach` method which traverses all the
   *  elements contained in the collection, applying a given function to each.
   *  They also need to provide a method `newBuilder`
   *  which creates a builder for collections of the same kind.
   *  
   *  A traversable class might or might not have two properties: strictness
   *  and orderedness. Neither is represented as a type.
   *  
   *  The instances of a strict collection class have all their elements
   *  computed before they can be used as values. By contrast, instances of
   *  a non-strict collection class may defer computation of some of their
   *  elements until after the instance is available as a value.
   *  A typical example of a non-strict collection class is a
   *  <a href="../immutable/Stream.html" target="ContentFrame">
   *  `scala.collection.immutable.Stream`</a>.
   *  A more general class of examples are `TraversableViews`.
   *  
   *  If a collection is an instance of an ordered collection class, traversing
   *  its elements with `foreach` will always visit elements in the
   *  same order, even for different runs of the program. If the class is not
   *  ordered, `foreach` can visit elements in different orders for
   *  different runs (but it will keep the same order in the same run).'
   * 
   *  A typical example of a collection class which is not ordered is a
   *  `HashMap` of objects. The traversal order for hash maps will
   *  depend on the hash codes of its elements, and these hash codes might
   *  differ from one run to the next. By contrast, a `LinkedHashMap`
   *  is ordered because it's `foreach` method visits elements in the
   *  order they were inserted into the `HashMap`.
   *

        <p>Handles AT&amp;T assembler syntax (more specifically this handles
        the GNU Assembler (gas) syntax.)
        It takes a single optional configuration parameter:
        <code>architecture</code>, which can be one of <code>"ARM"</code>,
        <code>"ARMv6"</code> or <code>"x86"</code>.
        Including the parameter adds syntax for the registers and special
        directives for the supplied architecture.

<h2>GFM mode</h2>
<form><textarea id="code" name="code">
GitHub Flavored Markdown
========================

Everything from markdown plus GFM features:

## URL autolinking

Underscores_are_allowed_between_words.

## Strikethrough text

GFM adds syntax to strikethrough text, which is missing from standard Markdown.

~~Mistaken text.~~
~~**works with other fomatting**~~

~~spans across
lines~~

## Fenced code blocks (and syntax highlighting)

```javascript
for (var i = 0; i &lt; items.length; i++) {
    console.log(items[i], i); // log them
}
```

## Task Lists

- [ ] Incomplete task list item
- [x] **Completed** task list item

## A bit of GitHub spice

    <p>The HTML mixed mode depends on the XML, JavaScript, and CSS modes.</p>

    <p>It takes an optional mode configuration
    option, <code>scriptTypes</code>, which can be used to add custom
    behavior for specific <code>&lt;script type="..."></code> tags. If
    given, it should hold an array of <code>{matches, mode}</code>
    objects, where <code>matches</code> is a string or regexp that
    matches the script type, and <code>mode</code> is
    either <code>null</code>, for script types that should stay in
    HTML mode, or a <a href="../../doc/manual.html#option_mode">mode
    spec</a> corresponding to the mode that should be used for the
    script.</p>

      JavaScript mode supports several configuration options:
      <ul>
        <li><code>json</code> which will set the mode to expect JSON
        data rather than a JavaScript program.</li>
        <li><code>jsonld</code> which will set the mode to expect
        <a href="http://json-ld.org">JSON-LD</a> linked data rather
        than a JavaScript program (<a href="json-ld.html">demo</a>).</li>
        <li><code>typescript</code> which will activate additional
        syntax highlighting and some other things for TypeScript code
        (<a href="typescript.html">demo</a>).</li>
        <li><code>statementIndent</code> which (given a number) will
        determine the amount of indentation to use for statements
        continued on a new line.</li>
        <li><code>wordCharacters</code>, a regexp that indicates which
        characters should be considered part of an identifier.
        Defaults to <code>/[\w$]/</code>, which does not handle
        non-ASCII identifiers. Can be set to something more elaborate
        to improve Unicode support.</li>

Getting the Gist of Markdown's Formatting Syntax
------------------------------------------------

This page offers a brief overview of what it's like to use Markdown.
The [syntax page] [s] provides complete, detailed documentation for
every feature, but Markdown should be very easy to pick up simply by
looking at a few examples of it in action. The examples on this page
are written in a before/after style, showing example syntax and the
HTML output produced by Markdown.

It's also helpful to simply try Markdown out; the [Dingus] [d] is a
web application that allows you type your own Markdown-formatted text
and translate it to XHTML.

**Note:** This document is itself written using Markdown; you
can [see the source for it by adding '.text' to the URL] [src].

  [s]: /projects/markdown/syntax  "Markdown Syntax"
  [d]: /projects/markdown/dingus  "Markdown Dingus"
  [src]: /projects/markdown/basics.text


## Paragraphs, Headers, Blockquotes ##

A paragraph is simply one or more consecutive lines of text, separated
by one or more blank lines. (A blank line is any line that looks like
a blank line -- a line containing nothing but spaces or tabs is
considered blank.) Normal paragraphs should not be indented with
spaces or tabs.

Markdown offers two styles of headers: *Setext* and *atx*.
Setext-style headers for `&lt;h1&gt;` and `&lt;h2&gt;` are created by
"underlining" with equal signs (`=`) and hyphens (`-`), respectively.
To create an atx-style header, you put 1-6 hash marks (`#`) at the
beginning of the line -- the number of hashes equals the resulting
HTML header level.

Blockquotes are indicated using email-style '`&gt;`' angle brackets.

Markdown:

    A First Level Header
    ====================
    
    A Second Level Header
    ---------------------

    Now is the time for all good men to come to
    the aid of their country. This is just a
    regular paragraph.

    The quick brown fox jumped over the lazy
    dog's back.
    
    ### Header 3

    &gt; This is a blockquote.
    &gt; 
    &gt; This is the second paragraph in the blockquote.
    &gt;
    &gt; ## This is an H2 in a blockquote


Output:

    &lt;h1&gt;A First Level Header&lt;/h1&gt;
    
    &lt;h2&gt;A Second Level Header&lt;/h2&gt;
    
    &lt;p&gt;Now is the time for all good men to come to
    the aid of their country. This is just a
    regular paragraph.&lt;/p&gt;
    
    &lt;p&gt;The quick brown fox jumped over the lazy
    dog's back.&lt;/p&gt;
    
    &lt;h3&gt;Header 3&lt;/h3&gt;
    
    &lt;blockquote&gt;
        &lt;p&gt;This is a blockquote.&lt;/p&gt;
        
        &lt;p&gt;This is the second paragraph in the blockquote.&lt;/p&gt;
        
        &lt;h2&gt;This is an H2 in a blockquote&lt;/h2&gt;
    &lt;/blockquote&gt;



### Phrase Emphasis ###

Markdown uses asterisks and underscores to indicate spans of emphasis.

Markdown:

    Some of these words *are emphasized*.
    Some of these words _are emphasized also_.
    
    Use two asterisks for **strong emphasis**.
    Or, if you prefer, __use two underscores instead__.

Output:

    &lt;p&gt;Some of these words &lt;em&gt;are emphasized&lt;/em&gt;.
    Some of these words &lt;em&gt;are emphasized also&lt;/em&gt;.&lt;/p&gt;
    
    &lt;p&gt;Use two asterisks for &lt;strong&gt;strong emphasis&lt;/strong&gt;.
    Or, if you prefer, &lt;strong&gt;use two underscores instead&lt;/strong&gt;.&lt;/p&gt;
   


## Lists ##

Unordered (bulleted) lists use asterisks, pluses, and hyphens (`*`,
`+`, and `-`) as list markers. These three markers are
interchangable; this:

    *   Candy.
    *   Gum.
    *   Booze.

this:

    +   Candy.
    +   Gum.
    +   Booze.

and this:

    -   Candy.
    -   Gum.
    -   Booze.

all produce the same output:

    &lt;ul&gt;
    &lt;li&gt;Candy.&lt;/li&gt;
    &lt;li&gt;Gum.&lt;/li&gt;
    &lt;li&gt;Booze.&lt;/li&gt;
    &lt;/ul&gt;

Ordered (numbered) lists use regular numbers, followed by periods, as
list markers:

    1.  Red
    2.  Green
    3.  Blue

Output:

    &lt;ol&gt;
    &lt;li&gt;Red&lt;/li&gt;
    &lt;li&gt;Green&lt;/li&gt;
    &lt;li&gt;Blue&lt;/li&gt;
    &lt;/ol&gt;

If you put blank lines between items, you'll get `&lt;p&gt;` tags for the
list item text. You can create multi-paragraph list items by indenting
the paragraphs by 4 spaces or 1 tab:

    *   A list item.
    
        With multiple paragraphs.

    *   Another item in the list.

Output:

    &lt;ul&gt;
    &lt;li&gt;&lt;p&gt;A list item.&lt;/p&gt;
    &lt;p&gt;With multiple paragraphs.&lt;/p&gt;&lt;/li&gt;
    &lt;li&gt;&lt;p&gt;Another item in the list.&lt;/p&gt;&lt;/li&gt;
    &lt;/ul&gt;
    


### Links ###

Markdown supports two styles for creating links: *inline* and
*reference*. With both styles, you use square brackets to delimit the
text you want to turn into a link.

Inline-style links use parentheses immediately after the link text.
For example:

    This is an [example link](http://example.com/).

Output:

    &lt;p&gt;This is an &lt;a href="http://example.com/"&gt;
    example link&lt;/a&gt;.&lt;/p&gt;

Optionally, you may include a title attribute in the parentheses:

    This is an [example link](http://example.com/ "With a Title").

Output:

    &lt;p&gt;This is an &lt;a href="http://example.com/" title="With a Title"&gt;
    example link&lt;/a&gt;.&lt;/p&gt;

Reference-style links allow you to refer to your links by names, which
you define elsewhere in your document:

    I get 10 times more traffic from [Google][1] than from
    [Yahoo][2] or [MSN][3].

    [1]: http://google.com/        "Google"
    [2]: http://search.yahoo.com/  "Yahoo Search"
    [3]: http://search.msn.com/    "MSN Search"

Output:

    &lt;p&gt;I get 10 times more traffic from &lt;a href="http://google.com/"
    title="Google"&gt;Google&lt;/a&gt; than from &lt;a href="http://search.yahoo.com/"
    title="Yahoo Search"&gt;Yahoo&lt;/a&gt; or &lt;a href="http://search.msn.com/"
    title="MSN Search"&gt;MSN&lt;/a&gt;.&lt;/p&gt;

The title attribute is optional. Link names may contain letters,
numbers and spaces, but are *not* case sensitive:

    I start my morning with a cup of coffee and
    [The New York Times][NY Times].

    [ny times]: http://www.nytimes.com/

Output:

    &lt;p&gt;I start my morning with a cup of coffee and
    &lt;a href="http://www.nytimes.com/"&gt;The New York Times&lt;/a&gt;.&lt;/p&gt;


### Images ###

Image syntax is very much like link syntax.

Inline (titles are optional):

    ![alt text](/path/to/img.jpg "Title")

Reference-style:

    ![alt text][id]

    [id]: /path/to/img.jpg "Title"

Both of the above examples produce the same output:

    &lt;img src="/path/to/img.jpg" alt="alt text" title="Title" /&gt;



### Code ###

In a regular paragraph, you can create code span by wrapping text in
backtick quotes. Any ampersands (`&amp;`) and angle brackets (`&lt;` or
`&gt;`) will automatically be translated into HTML entities. This makes
it easy to use Markdown to write about HTML example code:

    I strongly recommend against using any `&lt;blink&gt;` tags.

    I wish SmartyPants used named entities like `&amp;mdash;`
    instead of decimal-encoded entites like `&amp;#8212;`.

Output:

    &lt;p&gt;I strongly recommend against using any
    &lt;code&gt;&amp;lt;blink&amp;gt;&lt;/code&gt; tags.&lt;/p&gt;
    
    &lt;p&gt;I wish SmartyPants used named entities like
    &lt;code&gt;&amp;amp;mdash;&lt;/code&gt; instead of decimal-encoded
    entites like &lt;code&gt;&amp;amp;#8212;&lt;/code&gt;.&lt;/p&gt;


To specify an entire block of pre-formatted code, indent every line of
the block by 4 spaces or 1 tab. Just like with code spans, `&amp;`, `&lt;`,
and `&gt;` characters will be escaped automatically.

Markdown:

    If you want your page to validate under XHTML 1.0 Strict,
    you've got to put paragraph tags in your blockquotes:

        &lt;blockquote&gt;
            &lt;p&gt;For example.&lt;/p&gt;
        &lt;/blockquote&gt;

Output:

    &lt;p&gt;If you want your page to validate under XHTML 1.0 Strict,
    you've got to put paragraph tags in your blockquotes:&lt;/p&gt;
    
    &lt;pre&gt;&lt;code&gt;&amp;lt;blockquote&amp;gt;
        &amp;lt;p&amp;gt;For example.&amp;lt;/p&amp;gt;
    &amp;lt;/blockquote&amp;gt;
    &lt;/code&gt;&lt;/pre&gt;

/ utilities to quickly load a csv file - for more exhaustive analysis of the csv contents see csvguess.q
/ 2009.09.20 - updated to match latest csvguess.q 

/ .csv.colhdrs[file] - return a list of colhdrs from file
/ info:.csv.info[file] - return a table of information about the file
/ columns are: 
/	c - column name; ci - column index; t - load type; mw - max width; 
/	dchar - distinct characters in values; rule - rule that caught the type
/	maybe - needs checking, _could_ be say a date, but perhaps just a float?
/ .csv.info0[file;onlycols] - like .csv.info except that it only analyses <onlycols>
/ example:
/	info:.csv.info0[file;(.csv.colhdrs file)like"*price"]
/	info:.csv.infolike[file;"*price"]
/	show delete from info where t=" "
/ .csv.data[file;info] - use the info from .csv.info to read the data
/ .csv.data10[file;info] - like .csv.data but only returns the first 10 rows
/ bulkload[file;info] - bulk loads file into table DATA (which must be already defined :: DATA:() )
/ .csv.read[file]/read10[file] - for when you don't care about checking/tweaking the <info> before reading

<h2>reStructuredText mode</h2>
<form><textarea id="code" name="code">
.. This is an excerpt from Sphinx documentation: http://sphinx.pocoo.org/_sources/rest.txt

.. highlightlang:: rest

.. _rst-primer:

reStructuredText Primer
=======================

This section is a brief introduction to reStructuredText (reST) concepts and
syntax, intended to provide authors with enough information to author documents
productively.  Since reST was designed to be a simple, unobtrusive markup
language, this will not take too long.

.. seealso::

   The authoritative `reStructuredText User Documentation
   &lt;http://docutils.sourceforge.net/rst.html&gt;`_.  The "ref" links in this
   document link to the description of the individual constructs in the reST
   reference.


Paragraphs
----------

The paragraph (:duref:`ref &lt;paragraphs&gt;`) is the most basic block in a reST
document.  Paragraphs are simply chunks of text separated by one or more blank
lines.  As in Python, indentation is significant in reST, so all lines of the
same paragraph must be left-aligned to the same level of indentation.


.. _inlinemarkup:

Inline markup
-------------

The standard reST inline markup is quite simple: use

* one asterisk: ``*text*`` for emphasis (italics),
* two asterisks: ``**text**`` for strong emphasis (boldface), and
* backquotes: ````text```` for code samples.

If asterisks or backquotes appear in running text and could be confused with
inline markup delimiters, they have to be escaped with a backslash.

Be aware of some restrictions of this markup:

* it may not be nested,
* content may not start or end with whitespace: ``* text*`` is wrong,
* it must be separated from surrounding text by non-word characters.  Use a
  backslash escaped space to work around that: ``thisis\ *one*\ word``.

These restrictions may be lifted in future versions of the docutils.

reST also allows for custom "interpreted text roles"', which signify that the
enclosed text should be interpreted in a specific way.  Sphinx uses this to
provide semantic markup and cross-referencing of identifiers, as described in
the appropriate section.  The general syntax is ``:rolename:`content```.

Standard reST provides the following roles:

* :durole:`emphasis` -- alternate spelling for ``*emphasis*``
* :durole:`strong` -- alternate spelling for ``**strong**``
* :durole:`literal` -- alternate spelling for ````literal````
* :durole:`subscript` -- subscript text
* :durole:`superscript` -- superscript text
* :durole:`title-reference` -- for titles of books, periodicals, and other
  materials

See :ref:`inline-markup` for roles added by Sphinx.


Lists and Quote-like blocks
---------------------------

List markup (:duref:`ref &lt;bullet-lists&gt;`) is natural: just place an asterisk at
the start of a paragraph and indent properly.  The same goes for numbered lists;
they can also be autonumbered using a ``#`` sign::

   * This is a bulleted list.
   * It has two items, the second
     item uses two lines.

   1. This is a numbered list.
   2. It has two items too.

   #. This is a numbered list.
   #. It has two items too.


Nested lists are possible, but be aware that they must be separated from the
parent list items by blank lines::

   * this is
   * a list

     * with a nested list
     * and some subitems

   * and here the parent list continues

Definition lists (:duref:`ref &lt;definition-lists&gt;`) are created as follows::

   term (up to a line of text)
      Definition of the term, which must be indented

      and can even consist of multiple paragraphs

   next term
      Description.

Note that the term cannot have more than one line of text.

Quoted paragraphs (:duref:`ref &lt;block-quotes&gt;`) are created by just indenting
them more than the surrounding paragraphs.

Line blocks (:duref:`ref &lt;line-blocks&gt;`) are a way of preserving line breaks::

   | These lines are
   | broken exactly like in
   | the source file.

There are also several more special blocks available:

* field lists (:duref:`ref &lt;field-lists&gt;`)
* option lists (:duref:`ref &lt;option-lists&gt;`)
* quoted literal blocks (:duref:`ref &lt;quoted-literal-blocks&gt;`)
* doctest blocks (:duref:`ref &lt;doctest-blocks&gt;`)


Source Code
-----------

Literal code blocks (:duref:`ref &lt;literal-blocks&gt;`) are introduced by ending a
paragraph with the special marker ``::``.  The literal block must be indented
(and, like all paragraphs, separated from the surrounding ones by blank lines)::

   This is a normal text paragraph. The next paragraph is a code sample::

      It is not processed in any way, except
      that the indentation is removed.

      It can span multiple lines.

   This is a normal text paragraph again.

The handling of the ``::`` marker is smart:

* If it occurs as a paragraph of its own, that paragraph is completely left
  out of the document.
* If it is preceded by whitespace, the marker is removed.
* If it is preceded by non-whitespace, the marker is replaced by a single
  colon.

That way, the second sentence in the above example's first paragraph would be
rendered as "The next paragraph is a code sample:".


.. _rst-tables:

Tables
------

Two forms of tables are supported.  For *grid tables* (:duref:`ref
&lt;grid-tables&gt;`), you have to "paint" the cell grid yourself.  They look like
this::

   +------------------------+------------+----------+----------+
   | Header row, column 1   | Header 2   | Header 3 | Header 4 |
   | (header rows optional) |            |          |          |
   +========================+============+==========+==========+
   | body row 1, column 1   | column 2   | column 3 | column 4 |
   +------------------------+------------+----------+----------+
   | body row 2             | ...        | ...      |          |
   +------------------------+------------+----------+----------+

*Simple tables* (:duref:`ref &lt;simple-tables&gt;`) are easier to write, but
limited: they must contain more than one row, and the first column cannot
contain multiple lines.  They look like this::

   =====  =====  =======
   A      B      A and B
   =====  =====  =======
   False  False  False
   True   False  False
   False  True   False
   True   True   True
   =====  =====  =======


Hyperlinks
----------

External links
^^^^^^^^^^^^^^

Use ```Link text &lt;http://example.com/&gt;`_`` for inline web links.  If the link
text should be the web address, you don't need special markup at all, the parser
finds links and mail addresses in ordinary text.

You can also separate the link and the target definition (:duref:`ref
&lt;hyperlink-targets&gt;`), like this::

   This is a paragraph that contains `a link`_.

   .. _a link: http://example.com/


Internal links
^^^^^^^^^^^^^^

Internal linking is done via a special reST role provided by Sphinx, see the
section on specific markup, :ref:`ref-role`.


Sections
--------

Section headers (:duref:`ref &lt;sections&gt;`) are created by underlining (and
optionally overlining) the section title with a punctuation character, at least
as long as the text::

   =================
   This is a heading
   =================

Normally, there are no heading levels assigned to certain characters as the
structure is determined from the succession of headings.  However, for the
Python documentation, this convention is used which you may follow:

* ``#`` with overline, for parts
* ``*`` with overline, for chapters
* ``=``, for sections
* ``-``, for subsections
* ``^``, for subsubsections
* ``"``, for paragraphs

Of course, you are free to use your own marker characters (see the reST
documentation), and use a deeper nesting level, but keep in mind that most
target formats (HTML, LaTeX) have a limited supported nesting depth.


Explicit Markup
---------------

"Explicit markup" (:duref:`ref &lt;explicit-markup-blocks&gt;`) is used in reST for
most constructs that need special handling, such as footnotes,
specially-highlighted paragraphs, comments, and generic directives.

An explicit markup block begins with a line starting with ``..`` followed by
whitespace and is terminated by the next paragraph at the same level of
indentation.  (There needs to be a blank line between explicit markup and normal
paragraphs.  This may all sound a bit complicated, but it is intuitive enough
when you write it.)


.. _directives:

Directives
----------

A directive (:duref:`ref &lt;directives&gt;`) is a generic block of explicit markup.
Besides roles, it is one of the extension mechanisms of reST, and Sphinx makes
heavy use of it.

Docutils supports the following directives:

* Admonitions: :dudir:`attention`, :dudir:`caution`, :dudir:`danger`,
  :dudir:`error`, :dudir:`hint`, :dudir:`important`, :dudir:`note`,
  :dudir:`tip`, :dudir:`warning` and the generic :dudir:`admonition`.
  (Most themes style only "note" and "warning" specially.)

* Images:

  - :dudir:`image` (see also Images_ below)
  - :dudir:`figure` (an image with caption and optional legend)

* Additional body elements:

  - :dudir:`contents` (a local, i.e. for the current file only, table of
    contents)
  - :dudir:`container` (a container with a custom class, useful to generate an
    outer ``&lt;div&gt;`` in HTML)
  - :dudir:`rubric` (a heading without relation to the document sectioning)
  - :dudir:`topic`, :dudir:`sidebar` (special highlighted body elements)
  - :dudir:`parsed-literal` (literal block that supports inline markup)
  - :dudir:`epigraph` (a block quote with optional attribution line)
  - :dudir:`highlights`, :dudir:`pull-quote` (block quotes with their own
    class attribute)
  - :dudir:`compound` (a compound paragraph)

* Special tables:

  - :dudir:`table` (a table with title)
  - :dudir:`csv-table` (a table generated from comma-separated values)
  - :dudir:`list-table` (a table generated from a list of lists)

* Special directives:

  - :dudir:`raw` (include raw target-format markup)
  - :dudir:`include` (include reStructuredText from another file)
    -- in Sphinx, when given an absolute include file path, this directive takes
    it as relative to the source directory
  - :dudir:`class` (assign a class attribute to the next element) [1]_

* HTML specifics:

  - :dudir:`meta` (generation of HTML ``&lt;meta&gt;`` tags)
  - :dudir:`title` (override document title)

* Influencing markup:

  - :dudir:`default-role` (set a new default role)
  - :dudir:`role` (create a new role)

  Since these are only per-file, better use Sphinx' facilities for setting the
  :confval:`default_role`.

Do *not* use the directives :dudir:`sectnum`, :dudir:`header` and
:dudir:`footer`.

Directives added by Sphinx are described in :ref:`sphinxmarkup`.

Basically, a directive consists of a name, arguments, options and content. (Keep
this terminology in mind, it is used in the next chapter describing custom
directives.)  Looking at this example, ::

   .. function:: foo(x)
                 foo(y, z)
      :module: some.module.name

      Return a line of text input from the user.

``function`` is the directive name.  It is given two arguments here, the
remainder of the first line and the second line, as well as one option
``module`` (as you can see, options are given in the lines immediately following
the arguments and indicated by the colons).  Options must be indented to the
same level as the directive content.

The directive content follows after a blank line and is indented relative to the
directive start.


Images
------

reST supports an image directive (:dudir:`ref &lt;image&gt;`), used like so::

   .. image:: gnu.png
      (options)

When used within Sphinx, the file name given (here ``gnu.png``) must either be
relative to the source file, or absolute which means that they are relative to
the top source directory.  For example, the file ``sketch/spam.rst`` could refer
to the image ``images/spam.png`` as ``../images/spam.png`` or
``/images/spam.png``.

Sphinx will automatically copy image files over to a subdirectory of the output
directory on building (e.g. the ``_static`` directory for HTML output.)

Interpretation of image size options (``width`` and ``height``) is as follows:
if the size has no unit or the unit is pixels, the given size will only be
respected for output channels that support pixels (i.e. not in LaTeX output).
Other units (like ``pt`` for points) will be used for HTML and LaTeX output.

Sphinx extends the standard docutils behavior by allowing an asterisk for the
extension::

   .. image:: gnu.*

Sphinx then searches for all images matching the provided pattern and determines
their type.  Each builder then chooses the best image out of these candidates.
For instance, if the file name ``gnu.*`` was given and two files :file:`gnu.pdf`
and :file:`gnu.png` existed in the source tree, the LaTeX builder would choose
the former, while the HTML builder would prefer the latter.

.. versionchanged:: 0.4
   Added the support for file names ending in an asterisk.

.. versionchanged:: 0.6
   Image paths can now be absolute.


Footnotes
---------

For footnotes (:duref:`ref &lt;footnotes&gt;`), use ``[#name]_`` to mark the footnote
location, and add the footnote body at the bottom of the document after a
"Footnotes" rubric heading, like so::

   Lorem ipsum [#f1]_ dolor sit amet ... [#f2]_

   .. rubric:: Footnotes

   .. [#f1] Text of the first footnote.
   .. [#f2] Text of the second footnote.

You can also explicitly number the footnotes (``[1]_``) or use auto-numbered
footnotes without names (``[#]_``).


Citations
---------

Standard reST citations (:duref:`ref &lt;citations&gt;`) are supported, with the
additional feature that they are "global", i.e. all citations can be referenced
from all files.  Use them like so::

   Lorem ipsum [Ref]_ dolor sit amet.

   .. [Ref] Book or article reference, URL or whatever.

Citation usage is similar to footnote usage, but with a label that is not
numeric or begins with ``#``.


Substitutions
-------------

reST supports "substitutions" (:duref:`ref &lt;substitution-definitions&gt;`), which
are pieces of text and/or markup referred to in the text by ``|name|``.  They
are defined like footnotes with explicit markup blocks, like this::

   .. |name| replace:: replacement *text*

or this::

   .. |caution| image:: warning.png
                :alt: Warning!

See the :duref:`reST reference for substitutions &lt;substitution-definitions&gt;`
for details.

If you want to use some substitutions for all documents, put them into
:confval:`rst_prolog` or put them into a separate file and include it into all
documents you want to use them in, using the :rst:dir:`include` directive.  (Be
sure to give the include file a file name extension differing from that of other
source files, to avoid Sphinx finding it as a standalone document.)

Sphinx defines some default substitutions, see :ref:`default-substitutions`.


Comments
--------

Every explicit markup block which isn't a valid markup construct (like the
footnotes above) is regarded as a comment (:duref:`ref &lt;comments&gt;`).  For
example::

   .. This is a comment.

You can indent text after a comment start to form multiline comments::

   ..
      This whole indented block
      is a comment.

      Still in the comment.


Source encoding
---------------

Since the easiest way to include special characters like em dashes or copyright
signs in reST is to directly write them as Unicode characters, one has to
specify an encoding.  Sphinx assumes source files to be encoded in UTF-8 by
default; you can change this with the :confval:`source_encoding` config value.


Gotchas
-------

There are some problems one commonly runs into while authoring reST documents:

* **Separation of inline markup:** As said above, inline markup spans must be
  separated from the surrounding text by non-word characters, you have to use a
  backslash-escaped space to get around that.  See `the reference
  &lt;http://docutils.sf.net/docs/ref/rst/restructuredtext.html#inline-markup&gt;`_
  for the details.

* **No nested inline markup:** Something like ``*see :func:`foo`*`` is not
  possible.


.. rubric:: Footnotes

.. [1] When the default domain contains a :rst:dir:`class` directive, this directive
       will be shadowed.  Therefore, Sphinx re-exports it as :rst:dir:`rst-class`.

<p>Mode for Smarty version 2 or 3, which allows for custom delimiter tags.</p>

<p>Several configuration parameters are supported:</p>

<ul>
  <li><code>leftDelimiter</code> and <code>rightDelimiter</code>,
  which should be strings that determine where the Smarty syntax
  starts and ends.</li>
  <li><code>version</code>, which should be 2 or 3.</li>
  <li><code>baseMode</code>, which can be a mode spec
  like <code>"text/html"</code> to set a different background mode.</li>
</ul>

<p><strong>MIME types defined:</strong> <code>text/x-smarty</code></p>

{$foo.a.$b.c}     => $foo['a'][$b]['c']
{$foo.a.{$b+4}.c} => $foo['a'][$b+4]['c']

/*
  How Properties of Mime Types are used by SQL Mode
  =================================================

  keywords:
    A list of keywords you want to be highlighted.
  builtin:
    A list of builtin types you want to be highlighted (if you want types to be of class "builtin" instead of "keyword").
  operatorChars:
    All characters that must be handled as operators.
  client:
    Commands parsed and executed by the client (not the server).
  support:
    A list of supported syntaxes which are not common, but are supported by more than 1 DBMS.
    * ODBCdotTable: .tableName
    * zerolessFloat: .1
    * doubleQuote
    * nCharCast: N'string'
    * charsetCast: _utf8'string'
    * commentHash: use # char for comments
    * commentSlashSlash: use // for comments
    * commentSpaceRequired: require a space after -- for comments
  atoms:
    Keywords that must be highlighted as atoms,. Some DBMS's support more atoms than others:
    UNKNOWN, INFINITY, UNDERFLOW, NaN...
  dateSQL:
    Used for date/time SQL standard syntax, because not all DBMS's support same temporal types.

        \begin{spfcase}{$i=0$}
          \begin{spfstep}[display=flow]
            then $\livar{V}i=\set{\livar{v}r}$, where $\livar{v}r$ is the root, so

           By the \begin{justification}[method=byDef]definition of a binary

          \end{spfstep}

           As $G$ is \termref[cd=balanced-binary-trees,name=balanced-binary-tree]{balanced} and $\gdepth{G}=n>i$, $\livar{V}{i-1}$ cannot contain
            leaves.

      A fully balanced tree of depth $d$ has $\power2{d+1}-1$ nodes.

\begin{note}
  \begin{omtext}[type=conclusion,for=binary-tree]
    This shows that balanced binary trees grow in breadth very quickly, a consequence of
    this is that they are very shallow (and this compute very fast), which is the essence of
    the next result.

h2. Attributes

Layouts and phrase modifiers can be modified with various kinds of attributes: alignment, CSS ID, CSS class names, language, padding, and CSS styles.

h3. Alignment

div<. left align
div>. right align

h3. CSS ID and class name

You are a %(my-id#my-classname) rad% person.

h3. Language

p[en_CA]. Strange weather, eh?

h3. Horizontal Padding

p(())). 2em left padding, 3em right padding

h3. CSS styling

h2. Temporarily disabling textile markup

notextile. Don't __touch this!__

Surround text with double-equals to disable textile inline. Example: Use ==*asterisks*== for *strong* text.


h2. HTML

Some block layouts are simply textile versions of HTML tags with the same name, like @div@, @pre@, and @p@. HTML tags can also exist on their own line:

<section>
  <h1>Title</h1>
  <p>Hello!</p>
</section>

</textarea></form>
    <script>
        var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
            lineNumbers: true,
            mode: "text/x-textile"
        });
    </script>

!Hyperlinks
* [[WikiWords|WikiWord]] are automatically transformed to hyperlinks to the respective tiddler
** the automatic transformation can be suppressed by preceding the respective WikiWord with a tilde ({{{~}}}): {{{~WikiWord}}}
* [[PrettyLinks]] are enclosed in square brackets and contain the desired tiddler name: {{{[[tiddler name]]}}}
** optionally, a custom title or description can be added, separated by a pipe character ({{{|}}}): {{{[[title|target]]}}}<br>'''N.B.:''' In this case, the target can also be any website (i.e. URL).

!Custom Styling
* {{{@@CssProperty:value;CssProperty:value;...@@}}}<br>''N.B.:'' CSS color definitions should use lowercase letters to prevent the inadvertent creation of WikiWords.
* <html><code>{{customCssClass{...}}}</code></html>
* raw HTML can be inserted by enclosing the respective code in HTML tags: {{{<html> ... </html>}}}

!Special Markers

* {{{----}}} creates a horizontal ruler
* [[HTML entities|http://www.tiddlywiki.com/#HtmlEntities]]
* [[HTML entities local|HtmlEntities]]
* {{{<<macroName>>}}} calls the respective [[macro|Macros]]
* To hide text within a tiddler so that it is not displayed, it can be wrapped in {{{/%}}} and {{{%/}}}.<br/>This can be a useful trick for hiding drafts or annotating complex markup.
* To prevent wiki markup from taking effect for a particular section, that section can be enclosed in three double quotes: e.g. {{{"""WikiWord"""}}}.

\fBmkvextract\fR {mode} {source\-filename} [options] [extraction\-spec]
.SH "DESCRIPTION"
.PP
.B mkvextract
extracts specific parts from a
.I Matroska(TM)
file to other useful formats\&. The first argument,
\fBmode\fR, tells
\fBmkvextract\fR(1)
what to extract\&. Currently supported is the extraction of
tracks,
tags,
attachments,
chapters,
CUE sheets,
timecodes
and
cues\&. The second argument is the name of the source file\&. It must be a
Matroska(TM)
file\&. All following arguments are options and extraction specifications; both of which depend on the selected mode\&.
.SS "Common options"
.PP
The following options are available in all modes and only described once in this section\&.
.PP
\fB\-f\fR, \fB\-\-parse\-fully\fR
.RS 4
Sets the parse mode to \*(Aqfull\*(Aq\&. The default mode does not parse the whole file but uses the meta seek elements for locating the required elements of a source file\&. In 99% of all cases this is enough\&. But for files that do not contain meta seek elements or which are damaged the user might have to use this mode\&. A full scan of a file can take a couple of minutes while a fast scan only takes seconds\&.
.RE
.PP
\fB\-\-command\-line\-charset\fR \fIcharacter\-set\fR
.RS 4
Sets the character set to convert strings given on the command line from\&. It defaults to the character set given by system\*(Aqs current locale\&.
.RE
.PP
\fB\-\-output\-charset\fR \fIcharacter\-set\fR
.RS 4
Sets the character set to which strings are converted that are to be output\&. It defaults to the character set given by system\*(Aqs current locale\&.
.RE
.PP
\fB\-r\fR, \fB\-\-redirect\-output\fR \fIfile\-name\fR
.RS 4
Writes all messages to the file
\fIfile\-name\fR
instead of to the console\&. While this can be done easily with output redirection there are cases in which this option is needed: when the terminal reinterprets the output before writing it to a file\&. The character set set with
\fB\-\-output\-charset\fR
is honored\&.
.RE
.PP
\fB\-\-ui\-language\fR \fIcode\fR
.RS 4
Forces the translations for the language
\fIcode\fR
to be used (e\&.g\&. \*(Aqde_DE\*(Aq for the German translations)\&. It is preferable to use the environment variables
\fILANG\fR,
\fILC_MESSAGES\fR
and
\fILC_ALL\fR
though\&. Entering \*(Aqlist\*(Aq as the
\fIcode\fR
will cause
\fBmkvextract\fR(1)
to output a list of available translations\&.

#[[ hello steve
   This has invalid syntax that would normally need "poor man's escaping" like:

   #define()

   ${blah
]]#

#include( "disclaimer.txt" "opinion.txt" )
#include( $foo $bar )

#parse( "lecorbusier.vm" )
#parse( $foo )

#evaluate( 'string with VTL #if(true)will be displayed#end' )

#define( $hello ) Hello $who #end #set( $who = "World!") $hello ## displays Hello World!

#foreach( $customer in $customerList )

    $foreach.count $customer.Name

    #if( $foo == ${bar})
        it's true!
        #break
    #{else}
        it's not!
        #stop
    #end

    #if ($foreach.parent.hasNext)
        $velocityCount
    #end
#end

$someObject.getValues("this is a string split
        across lines")

$someObject("This plus $something in the middle").method(7567).property

#macro( tablerows $color $somelist )
    #foreach( $something in $somelist )
        <tr><td bgcolor=$color>$something</td></tr>
        <tr><td bgcolor=$color>$bodyContent</td></tr>
    #end
#end

#tablerows("red" ["dadsdf","dsa"])
#@tablerows("red" ["dadsdf","dsa"]) some body content #end

   Variable reference: #set( $monkey = $bill )
   String literal: #set( $monkey.Friend = 'monica' )
   Property reference: #set( $monkey.Blame = $whitehouse.Leak )
   Method reference: #set( $monkey.Plan = $spindoctor.weave($web) )
   Number literal: #set( $monkey.Number = 123 )
   Range operator: #set( $monkey.Numbers = [1..3] )
   Object list: #set( $monkey.Say = ["Not", $my, "fault"] )
   Object map: #set( $monkey.Map = {"banana" : "good", "roast beef" : "bad"})

The RHS can also be a simple arithmetic expression, such as:
Addition: #set( $value = $foo + 1 )
   Subtraction: #set( $value = $bar - 1 )
   Multiplication: #set( $value = $foo * $bar )
   Division: #set( $value = $foo / $bar )
   Remainder: #set( $value = $foo % $bar )

    &lt;title&gt;HTML Example&lt;/title&gt;

  &lt;body&gt;
    The indentation tries to be &lt;em&gt;somewhat &amp;quot;do what
    I mean&amp;quot;&lt;/em&gt;... but might not match your style.
  &lt;/body&gt;
&lt;/html&gt;

    </script>
    <p>The XML mode supports two configuration parameters:</p>
    <dl>
      <dt><code>htmlMode (boolean)</code></dt>
      <dd>This switches the mode to parse HTML instead of XML. This
      means attributes do not have to be quoted, and some elements
      (such as <code>br</code>) do not require a closing tag.</dd>
      <dt><code>alignCDATA (boolean)</code></dt>
      <dd>Setting this to true will force the opening tag of CDATA
      blocks to not be indented.</dd>
    </dl>

    <p><strong>MIME types defined:</strong> <code>application/xml</code>, <code>text/html</code>.</p>

  Transforms an XML element into a JSON string representation.  See http://json.org.
  &lt;p/&gt;
  Sample usage:
  &lt;pre&gt;
    xquery version &quot;1.0-ml&quot;;
    import module namespace json=&quot;http://marklogic.com/json&quot; at &quot;json.xqy&quot;;
    json:serialize(&amp;lt;foo&amp;gt;&amp;lt;bar&amp;gt;kid&amp;lt;/bar&amp;gt;&amp;lt;/foo&amp;gt;)
  &lt;/pre&gt;
  Sample transformations:
  &lt;pre&gt;
  &amp;lt;e/&amp;gt; becomes {&quot;e&quot;:null}
  &amp;lt;e&amp;gt;text&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:&quot;text&quot;}
  &amp;lt;e&amp;gt;quote &quot; escaping&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:&quot;quote \&quot; escaping&quot;}
  &amp;lt;e&amp;gt;backslash \ escaping&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:&quot;backslash \\ escaping&quot;}
  &amp;lt;e&amp;gt;&amp;lt;a&amp;gt;text1&amp;lt;/a&amp;gt;&amp;lt;b&amp;gt;text2&amp;lt;/b&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:{&quot;a&quot;:&quot;text1&quot;,&quot;b&quot;:&quot;text2&quot;}}
  &amp;lt;e&amp;gt;&amp;lt;a&amp;gt;text1&amp;lt;/a&amp;gt;&amp;lt;a&amp;gt;text2&amp;lt;/a&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:{&quot;a&quot;:[&quot;text1&quot;,&quot;text2&quot;]}}
  &amp;lt;e&amp;gt;&amp;lt;a array=&quot;true&quot;&amp;gt;text1&amp;lt;/a&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:{&quot;a&quot;:[&quot;text1&quot;]}}
  &amp;lt;e&amp;gt;&amp;lt;a type=&quot;boolean&quot;&amp;gt;false&amp;lt;/a&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:{&quot;a&quot;:false}}
  &amp;lt;e&amp;gt;&amp;lt;a type=&quot;number&quot;&amp;gt;123.5&amp;lt;/a&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:{&quot;a&quot;:123.5}}
  &amp;lt;e quote=&quot;true&quot;&amp;gt;&amp;lt;div attrib=&quot;value&quot;/&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:&quot;&amp;lt;div attrib=\&quot;value\&quot;/&amp;gt;&quot;}
  &lt;/pre&gt;
  &lt;p/&gt;
  Namespace URIs are ignored.  Namespace prefixes are included in the JSON name.
  &lt;p/&gt;
  Attributes are ignored, except for the special attribute @array=&quot;true&quot; that
  indicates the JSON serialization should write the node, even if single, as an
  array, and the attribute @type that can be set to &quot;boolean&quot; or &quot;number&quot; to
  dictate the value should be written as that type (unquoted).  There's also
  an @quote attribute that when set to true writes the inner content as text
  rather than as structured JSON, useful for sending some XHTML over the
  wire.
  &lt;p/&gt;
  Text nodes within mixed content are ignored.

  @param $x Element node to convert
  @return String holding JSON serialized representation of $x

  <p>This is a list of every mode in the distribution. Each mode lives
in a subdirectory of the <code>mode/</code> directory, and typically
defines a single JavaScript file that implements the mode. Loading
such file will make the language available to CodeMirror, through

 * Helper to test CodeMirror highlighting modes. It pretty prints output of the
 * highlighter and can check against expected styles.
 *
 * Mode tests are registered by calling test.mode(testName, mode,
 * tokens), where mode is a mode object as returned by
 * CodeMirror.getMode, and tokens is an array of lines that make up
 * the test.
 *
 * These lines are strings, in which styled stretches of code are
 * enclosed in brackets `[]`, and prefixed by their style. For
 * example, `[keyword if]`. Brackets in the code itself must be
 * duplicated to prevent them from being interpreted as token
 * boundaries. For example `a[[i]]` for `a[i]`. If a token has
 * multiple styles, the styles must be separated by ampersands, for
 * example `[tag&error </hmtl>]`.
 *
 * See the test.js files in the css, markdown, gfm, and stex mode
 * directories for examples.

        # How to contribute

- [Getting help](#getting-help-)
- [Submitting bug reports](#submitting-bug-reports-)
- [Contributing code](#contributing-code-)

## Getting help

Community discussion, questions, and informal bug reporting is done on the
[discuss.CodeMirror forum](http://discuss.codemirror.net).

## Submitting bug reports

The preferred way to report bugs is to use the
[GitHub issue tracker](http://github.com/codemirror/CodeMirror/issues). Before
reporting a bug, read these pointers.

**Note:** The issue tracker is for *bugs*, not requests for help. Questions
should be asked on the
[discuss.CodeMirror forum](http://discuss.codemirror.net) instead.

### Reporting bugs effectively

- CodeMirror is maintained by volunteers. They don't owe you anything, so be
  polite. Reports with an indignant or belligerent tone tend to be moved to the
  bottom of the pile.

- Include information about **the browser in which the problem occurred**. Even
  if you tested several browsers, and the problem occurred in all of them,
  mention this fact in the bug report. Also include browser version numbers and
  the operating system that you're on.

- Mention which release of CodeMirror you're using. Preferably, try also with
  the current development snapshot, to ensure the problem has not already been
  fixed.

- Mention very precisely what went wrong. "X is broken" is not a good bug
  report. What did you expect to happen? What happened instead? Describe the
  exact steps a maintainer has to take to make the problem occur. We can not
  fix something that we can not observe.

- If the problem can not be reproduced in any of the demos included in the
  CodeMirror distribution, please provide an HTML document that demonstrates
  the problem. The best way to do this is to go to
  [jsbin.com](http://jsbin.com/ihunin/edit), enter it there, press save, and
  include the resulting link in your bug report.

## Contributing code

- Make sure you have a [GitHub Account](https://github.com/signup/free)
- Fork [CodeMirror](https://github.com/codemirror/CodeMirror/)
  ([how to fork a repo](https://help.github.com/articles/fork-a-repo))
- Make your changes
- If your changes are easy to test or likely to regress, add tests.
  Tests for the core go into `test/test.js`, some modes have their own
  test suite under `mode/XXX/test.js`. Feel free to add new test
  suites to modes that don't have one yet (be sure to link the new
  tests into `test/index.html`).
- Follow the general code style of the rest of the project (see
  below). Run `bin/lint` to verify that the linter is happy.
- Make sure all tests pass. Visit `test/index.html` in your browser to
  run them.
- Submit a pull request
([how to create a pull request](https://help.github.com/articles/fork-a-repo))

### Coding standards

- 2 spaces per indentation level, no tabs.
- Include semicolons after statements.
- Note that the linter (`bin/lint`) which is run after each commit
  complains about unused variables and functions. Prefix their names
  with an underscore to muffle it.

- CodeMirror does *not* follow JSHint or JSLint prescribed style.
  Patches that try to 'fix' code to pass one of these linters will be
  unceremoniously discarded.

  <h2>Browser support</h2>
  <p>The <em>desktop</em> versions of the following browsers,
  in <em>standards mode</em> (HTML5 <code>&lt;!doctype html></code>
  recommended) are supported:</p>
  <table style="margin-bottom: 1em">
    <tr><th>Firefox</th><td>version 4 and up</td></tr>
    <tr><th>Chrome</th><td>any version</td></tr>
    <tr><th>Safari</th><td>version 5.2 and up</td></tr>
    <tr><th style="padding-right: 1em;">Internet Explorer</th><td>version 8 and up</td></tr>
    <tr><th>Opera</th><td>version 9 and up</td></tr>
  </table>
  <p>Support for modern mobile browsers is experimental. Recent
  versions of the iOS browser and Chrome on Android should work
  pretty well.</p>

        // When adding more parser context flags, consider which is the more common case that the

        // grammar specification.

        // An important thing about these context concepts.  By default they are effectively inherited
        // while parsing through every grammar production.  i.e. if you don't change them, then when
        // you parse a sub-production, it will have the same context values as the parent production.
        // This is great most of the time.  After all, consider all the 'expression' grammar productions
        // and how nearly all of them pass along the 'in' and 'yield' context values:
        //
        // EqualityExpression[In, Yield] :
        //      RelationalExpression[?In, ?Yield]

        //
        // Where you have to be careful is then understanding what the points are in the grammar
        // where the values are *not* passed along.  For example:
        //
        // SingleNameBinding[Yield,GeneratorParameter]
        //      [+GeneratorParameter]BindingIdentifier[Yield] Initializer[In]opt
        //      [~GeneratorParameter]BindingIdentifier[?Yield]Initializer[In, ?Yield]opt

        // explicitly set the 'yield' context flag to false before calling into the BindingIdentifier
        // and we should explicitly unset the 'yield' context flag before calling into the Initializer.

        // should leave the 'yield' context flag alone.
        //
        // Getting this all correct is tricky and requires careful reading of the grammar to
        // understand when these values should be changed versus when they should be inherited.
        //
        // Note: it should not be necessary to save/restore these flags during speculative/lookahead
        // parsing.  These context flags are naturally stored and restored through normal recursive
        // descent parsing and unwinding.

        //    character that was completely not understood.

    # portabled v0.6.1a

Self-editing filesystem embedded in a single HTML file.

The idea, all of the painstaking implementation and the vision by [Oleg Mihailik](mailto:mihailik@gmail.com).
See the credits section for the used libraries and respective licences.

### Outstanding tasks:
 * Unifying of all import/export into 'moreDialog'.
 * Download/upload for GitHub, GDrive, Dropbox etc.
 * Extra power in Chrome app, node-webkit, HTMLA-ie7: I/O to the actual filesystem.
 * Delete folder.
 * Rename file/folder.
 * Saving current position in documents.
 * TypeScript extra features: navigate to, search integration, tooltips.
 * Sub-domains for TypeScript/JavaScript completion/build contexts.
 * Doc handlers in plugins, plugin API and isolation (using iframes with their own 'global' and 'require').
 * node.js emulation for plugins and dependencies, allowing non-doc plugins.
 * Highlight of **changes** in files.
 * Styles and colours (planning for pale seaside 'Whitstable' blue, maybe black theme too).
 * Scrollbar to use syntax-highlighted document lines.
 * Toast popup/fadeout messages for key events: opening, building, import-export completion.
 * Add whole raw TypeScript repository sample.
